Title: An improved method of refrigerating an enclosed space having an access opening
IPC: F24F9/00
Filed: 1963-03-15
Abstract: 1,039,103. Refrigerators; defrosting. DUAL JET REFRIGERATION CO. March 15, 1963 [April 9, 1962], No. 10391/63. Heading F4H. In an open-fronted refrigerator in which air is circulated in inner and outer channels in the walls of the cabinet and is projected as separate panels across the front opening, the inner channel contains an evaporator which is defrosted for short periods of time at short time intervals and for long periods of time at long time intervals. As shown, three channels are provided, the inner channel containing an evaporator 50 and the intermediate channel an evaporator 53. The evaporators form part of the refrigeration system of Fig. 3 (not shown) in which evaporator 50 is arranged to be defrosted by hot gas supplied through a line 132 having a heater 134 and valves 122 and 122a are provided for cutting off liquid refrigerant flow to evaporators 50 and 53 respectively. The heater 134 is located immediately upstream of the outlet of the inner air panel and the inner and intermediate channels have dampers 202, 201 and 203, 204 upstream and downstream of their respective evaporators. At three hourly intervals valve 122 is closed, heater 134 is energized, dampers 201-204 are closed and hot gas is supplied to evaporator 50 for about three minutes. Upon termination of hot gas flow, dampers 201-204 and valve 122 are sequentially opened and heater 134 is turned off so that normal operation is resumed. Before the next defrost cycle valve 122a is opened to supply refrigerant to evaporator 53 to cool the intermediate air panel, the valve being closed before the defrost cycle is initiated. At about twenty-four hourly intervals the above cycle is repeated except that hot gas is supplied to evaporator 50 for about seventeen minutes. In a modification (Fig. 1, not shown), the dampers 76, 78 and 86, 88 upstream and downstream of the evaporators are so associated with cross-over channels that, between hot-gas defrosts, relatively warm air from the intermediate air panel may be circulated over evaporator 50 while air from the inner panel circulates over evaporator 53.

IPC: B23K33/00
Abstract: 105,572. Walker, W. H., (Assignee of Smith, H. M., and Stanley, W. W.). April 14, 1916, [Convention date]. Welding.-In joining relatively thin flexible sheet-metal edges, a limited area of initial contact is first provided, and the parts are then superposed, electrically heated, and forged so that the welded area is progressively increased. To produce vacuum-tight joints of uniform thickness as required in certain cylindrical parts for vacuum bottles, cartridge shells, shell cases, &c., the metal edges a, b are bevelled off parallel to one another, Fig. 4, and one edge portion is bent laterally and the sheet arranged as shown in Fig. 6. The joint is then arranged between a fixed or wheel electrode 5 and a roller electrode 2, the peripheral face of which is parallel to the bevel face 14, thus providing large contact surface and consequently small resistance. The joint is finally rolled flat, Fig. 9. Fig. 4a shows the use of a mandrel expanded by a wedge 31 as an electrode. Modifications are described wherein the edges are not parallel, or are rounded off, or only one edge is tapered and rounded. In the construction shown in Fig. 13, the part 22 acts as an electrode, and the cylindrical part 21 is provided with a transverse ridge 23 and a depression 24. In an. other modification, the ridge is laterally arranged. The welded parts may be of any prescribed contour and the welding effected in air or other gas or liquid. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification in which the edges of both sheets are bent upwards prior to roll welding. In another modification one sheet is plain and is lapped over the second sheet which has a longitudinal rounded ridge with round bottom grooves at each side thereof. This subjectmatter does not appear in the Specification as accepted.

IPC: H02H9/02
Filed: 1966-03-10
Abstract: 1,086,389. Protective arrangements. MULLARD Ltd. March 10, 1966, No. 10572/66. Heading H2H. [Also in Division G3] The load current taken by a furnace (not shown) is monitored by transformers 1, 2, 3 which are connected over a rectifier bridge 4 to 9 and a diode 11 to a capacitor 10 which is thus charged in dependence upon the load current; if this load current rises to an excessive value, the voltage on capacitor 10 becomes sufficiently high to allow current to flow through a voltagedependent resistor 12 and a resistor 13 to the base of a transistor 14 which is thereby rendered conductive so that the signal at output terminals 15 is reduced. Terminals 15 are connected to trigger modules for thyristors (not shown) controlling the furnace current, the thyristors normally being controlled in dependence upon temperature variations as detected by sensing means having an output which is applied to terminals 24. A fall in the signal level of terminals 15 causes a current reduction in the load, and the circuit shown thus operates as an excess current protection circuit. A further transistor 20 connected to a voltage source 26 is arranged so that the capacitor 10 is charged to a level sufficient to operate transistor 14 before the furnace is energized, and this prevents current overloads due to starting surges. To prevent damage by current surges during operation, a capacitor 27 is provided to slow down the rate of charge of the signal applied to terminals 13.

Title: Improvements in or relating to automatic control valves for fluid pressure brakes
IPC: B60T17/18
Filed: 1929-04-05
Abstract: 330,050. Withers, J. S., (Automatic Safety Control, Inc.). April 5, 1929. Fluid - pressure.- A vent valve comprises a chamber 14 in the train pipe 13 and a valve 44 closed by the train pipe pressure and opened by a spring 41 when this pressure is reduced and means responsive to this reduced pressure to close the vent valve after the air in the chamber has been vented through the vent valve. When the apparatus is charged, train pipe pressure fluid raises a check valve 33, passing into a chamber A and moving a piston 26 against a spring 23. This movement brings a seat 46 and a trigger 37 on the piston rod in the path of the valve 44 as shown. When train pipe pressure is reduced to a predetermined value the valve 44 is opened by the spring 41 and vents the train pipe through an air vent 39 also the valve head strikes the trigger 37 'which opens the check valve 33 to free the air in the chamber A. When the pressure in the chamber A is reduced to a predetermined valve the spring 23 pushes back the piston 26 and reseats the valve 44. A gasket 24 preventing leakage past the piston rod 18 is held in place by a sleeve 25 threaded in the cylinder 15. A flexible diaphragm 31 clamped at its edges is held to the piston by a hollow plug 28.

Filed: 1949-04-23
Abstract: 697,085. Automatic balancing control systems. KAHN, L. M., and KAHN, F. J. July 24, 1950 [April 23, 1949], No. 10826/49. Drawings to Specification. Class 38 (iv). [Also in Group II] The balance of a rotary hollow member is corrected by injecting liquid into one or more pockets provided in the member, the supply of liquid being controlled by a master valve shunted by a by-pass. The invention is applied to a modification of the hydro-extractor shown in Figs. 1-5 of Specification 682,769 in which solenoid-operated valves control the flow to each pocket and the master valve is incorporated in the pipe leading to the solenoidoperated valves. The electric circuit shown in Fig. 5 of Specification 682,769 is modified so that closure of the circuit as a result of vibration causes liquid to flow through the by-pass to one or more of the pockets. If the vibration continues for more than a given period, a time delay in the circuit causes the master valve to open to supply a greater quantity of liquid and the driving motor of the extractor to be cut off. In a modification a solenoidoperated valve is fitted in the by-pass, the circuit being further modified so that liquid does . not flow through the by-pass until after a given period, and the pump supplying the liquid operates only when the master valve or by-pass valve are open. Specification 663,829, [Group II], also is referred to.

In a pump comprising a rotatable cylinder block 12, Fig. 2, having a plurality of parallel cylinder bores 13 reciprocably mounting pistons 14 bearing against an inclined disc 15, the disc 15 is mounted for rotation about an axis 16 inclined at an angle co with respect to the face 17 of a fixed hollow casing 10 in which suction and delivery ports 18, 19 are formed. The disc is shown with its diameter of maximum slope coincident with the axis 16 and with the top and bottom dead centres occurring when the axes of diametrically opposite cylinders lie on a line YY, Fig. 3, projected from the axis 16 and symmetrically disposed with respect to the ports 18, 19. The pump output is then zero. On rotation of the disc,the diameter of maximum slope moves, e.g., so that projection XX is at an angle # to the line YY to vary pump output and the distributor timing to avoid sudden pressure variations when the cylinders move from the suction to the delivery zone and vice versa. Maximum output occurs when the projection of the diameter of maximum slope lies along a'line EF midway between the ports 18, 19. A lever 20 rotating the disc may be operated manually or automatically.
